You can put this solution on YOUR website!
You have 7 digits to choose from. After using one of them, you will only have 6 and after using another, you will only have 5. So this means that the number of possible combinations are\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7*6*5 = 42*5 = 210\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So there are 210 ways that a three digit number can be formed using the digits 0,1,2,3,4,5,6 and repetition is not allowed
